Abstract: The oil quality used in a machine, vehicle or system can be determined in response to determining a temperature and pressure within an oil supply. Once the oil quality is determined, an oil quality warning light can be activated, indicating the need to change the oil.

Abstract: Coatings containing at least 85% by volume crystalline mullite with less than 15% by volume of amorphous material and mullite dissociation phases are plasma sprayed onto the surface of a silicon based ceramic substrate by closely controlling the plasma spray parameters including the mullite feed stock and its particle size, the nozzle outlet stand-off distance, movement of the substrate past the plasma flow, back side heating of the substrate and the powder feed rate through the plasma spray gun.

Abstract: An elevator safety brake for stopping an elevator car is provided with a brake shoe having a molybdenum alloy friction surface for contacting an elevator guide rail surface to provide a stopping force. The molybdenum alloy contains 99.4 weight percent molybdenum, 0.5 weight percent titanium and 0.1 weight percent zirconium. The friction surface of the brake formed from the alloy exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.

Abstract: An elevator safety brake for stopping an elevator car is provided with a brake shoe having a carbon-carbon composite friction surface for contacting an elevator guide rail surface to provide a stopping force. The friction surface of the brake formed from the carbon-carbon composite exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.

Abstract: An elevator safety brake for stopping an elevator car is provided with a brake shoe having a fused sprayed friction coating for contacting an elevator guide rail surface to provide a stopping force. In a preferred embodiment, the coating is obtained by plasma spraying an admixture of 85 weight percent nickel-chromium alloy particles and 15 weight percent tungsten carbide particles on a substrate. The plasma sprayed admixture is fused. The fused sprayed friction surface of the brake exhibits a consistent high friction and low wear suitably accommodating high speed, high load elevators installed in very tall buildings.

Abstract: An elevator safety brake is provided comprising two cantilevers, a pivot, a spring, and a hold-off-engagement linkage. In one embodiment, the hold-off-engagement linkage is comprised of two upper struts, and two lower struts. When it is desired to slow or stop the elevator via the safety brake, the lower struts move from a first position in which the lower struts are substantially in alignment with one another and the cantilevers are in an open position, to a second position in which the lower struts are not substantially in alignment with one another and the cantilevers are in a closed position. When the cantilevers are in the closed position, the spring exerts a force via the cantilevers on the guide rail in order to decelerate the elevator.
